Description

Territory of invention

The The invention relates to the use of esters of 2-propylheptanol in cosmetic and / or pharmaceutical preparations as well as specific ones Esters and a process for their preparation.

in the Range of cosmetic emulsions for skin and hair care consumers make a variety of demands: Aside from the cleansing and nourishing effects that the application purpose value is placed on as different parameters as possible dermatological compatibility, good moisturizing Characteristics, elegant appearance, optimal sensory Impression and storage stability placed.

Preparations used to cleanse and care for human skin and hair usually contain a number of surfactants, especially oil and water. As Ölkörperl / emollients, for example, hydrocarbons, ester oils and vegetable and animal oils / fats / waxes are used. In order to meet the high demands of the market with regard to sensory properties and optimal dermatological compatibility, new oil bodies and emulsifier mixtures are continuously being developed and tested. The use of ester oils in cosmetics has long been known. Because of their importance, new processes are continuously being developed for their production. Branched ester oils, in particular, impart a "lighter" sensation to the skin and are therefore being intensively investigated.The use of 2-methyl-1,3-propanediol monoesters is, for example, the subject of DE 101 60 681 , the use of 2-methyl-1,3-propanedioldiestern is in the DE 10160 682 described.

The object of the present invention was to provide new ester oils which are liquid at 20 ° C. for cosmetic applications which have an improved profile with respect to the sensory properties (lightness) and can be incorporated into a large number of cosmetic formulations. Surprisingly, it has been found that esters of 2-propylheptanol lead to sensory light products. Some of these esters and their preparation are from the DE 103 05 562 known, but for a completely different application purpose, as polymer additives.

description the invention
